Prognosis

Note:

• A third of patients who attend hospital with syncope have another episode, many within one year. (34%: 95% CI: 29% to 38%) ^a
• Patients typically have more than one recurrence - in one study a mean of 7 over 2.5 years ^a
• However, no one specific cause of syncope favours recurrence, and recurrent syncope is not clearly associated with death or major morbidity. ^a
• Recurrent syncope is associated with raised levels of psychosocial and physical distress ^c
